with \(_{H00}\)  given by (REF ). This displaces the cell edge prediction poleward by, for example, \(\sim \) 19% if \({=0.5}\)  or \(\sim \) 50% if \({=0.2}\) . Using the original \({H=10}\)  km and \({=1/8}\)  parameter values from [1]} yields \({\approx 0.46}\)  and \(_{H00}\approx 28^\circ \) , which becomes approximately 33.3 if \({=0.5}\)  or 41.9 if \({=0.2}\) . This poleward displacement as \(\)  decreases adheres to physical intuition: because the upper-layer zonal wind magnitude at each latitudes decreases as \(\)  decreases, the two-layer baroclinic instability onset criterion is met farther poleward.
